BACKGROUND: We attempt to develop a relatively comprehensive structural model of risk factors for drug abuse (DA) in Swedish men that illustrates developmental and mediational processes. METHODS: We examined 20 risk factors for DA in 48,369 men undergoing conscription examinations in 1969-70 followed until 2011 when 2.34% (n=1134) of them had DA ascertained in medical, criminal and pharmacy registries. Risk factors were organized into four developmental tiers reflecting i) birth, ii) childhood/early adolescence, iii) late adolescence, and iv) young adulthood...

BACKGROUND: The first year of university attendance represents a critical time frame for the development of alcohol use and misuse given changes in autonomy and increased access to alcohol. Prior studies have demonstrated that the establishment of drinking patterns during this period is impacted by an array of demographic, environmental, and familial factors. It is critical to consider such factors jointly, and to understand potentially differential effects on stages of alcohol use/misuse, in order to identify robust predictors that may be targeted in prevention and intervention programming...

OBJECTIVE: Distress tolerance (DT; the perceived or actual ability to withstand negative internal states) has emerged as a promising transdiagnostic risk factor in clinically severe populations. However, little is known about etiological factors associated with the development of DT. We hypothesized that greater levels of childhood trauma would be associated with lower perceived and behavioral DT, beyond theoretically relevant covariates. METHOD: The current investigation evaluated several childhood trauma types (i...

BACKGROUND AND AIMS: The DSM-IV Personality Disorders (PDs) are comorbid with Alcohol Use Disorder (AUD) and with each other. It remains unclear which PD criteria are most likely to drive onset and recurrence of AUD and which are merely confounded with those criteria. We determine which individual PD criteria predict AUD and the degree of underlying genetic and/or environmental etiology. DESIGN: A prospective observational twin study. SETTING: Norway 1999-2011...

BACKGROUND AND OBJECTIVES: Given moderate heritability and significant heterogeneity among addiction phenotypes, successful genome-wide association studies (GWAS) are expected to need very large samples. As sample sizes grow, so can genetic diversity leading to challenges in analyzing these data. Methods for empirically assigning individuals to genetically informed ancestry groups are needed. METHODS: We describe a strategy for empirically assigning ancestry groups in ethnically diverse GWAS data including extensions of principal component analysis (PCA) and population matching through minimum Mahalanobis distance...

Twin studies show the established relation between bulimic symptoms and problematic alcohol involvement in adult females is partly due to shared familial factors, specifically shared genetic effects. However, it is unclear if similar shared etiological factors exist during adolescence or in males. We examined the familial overlap (i.e., genetic and common environmental correlations) between bulimic symptoms and various levels of alcohol involvement in 16- to 17-year-old female and male same-sex twin pairs using sex-specific biometrical twin modeling...

OBJECTIVE: The authors sought to determine whether pregnancy is an intrinsic motivator for cessation of drug abuse. METHOD: The authors conducted prospective cohort, co-relative, co-spouse, and within-person analyses of registration for drug abuse during pregnancy among Swedish women born between 1980 and 1990 who gave birth between ages 20 and 35 (N=149,512). Drug abuse was assessed from medical, criminal, and pharmacy registries. RESULTS: In the population, rates of drug abuse were lower during pregnancy (unadjusted odds ratio=0...

OBJECTIVE: The majority of studies that have examined parental alcohol use and offspring outcomes have either focused on exposure in the antenatal period or from clinical populations. This study sought to examine proximal and distal associations between parental alcohol use and offspring conduct problems and depressive symptoms in a population birth cohort. METHODS: We used prospective data from a large UK based population cohort (ALSPAC) to investigate the association between parental alcohol use, measured in units, (assessed at ages 4 and 12 years) with childhood conduct trajectories, (assessed on six occasions from 4 to 13...

Using information from Swedish population registries, we attempt to decompose the shared environment (C) into four subcomponents: close family, family, household, and community. Among pairs differing in their genetic and geographical/household relationships, we examine three externalizing syndromes: drug abuse (DA), criminal behavior (CB), and alcohol use disorders (AUD). The best-fitting common pathway model suggested that total estimates for C were higher for DA (21% for males and 18% for females) than for AUD (16% and 14%) and CB (17% and 10%)...

PURPOSE: Nationwide data have been lacking on drug abuse (DA)-associated mortality. We do not know the degree to which this excess mortality results from the characteristics of drug-abusing individuals or from the effects of DA itself. METHOD: DA was assessed from medical, criminal, and prescribed drug registries. Relative pairs discordant for DA were obtained from the Multi-Generation and Twin Registers. Mortality was obtained from the Swedish Mortality registry...

Alcohol use disorder (AUD) and major depressive disorder (MDD) are often comorbid. It is not understood how genetic risk factors for these disorders relate to each other over time and to what degree they are stable. Age-dependent characteristics of the disorders indicate that different genetic factors could be relevant at different stages of life, and MDD may become increasingly correlated with AUD over time. DSM-IV diagnoses of AUD and MDD were assessed by interviews of 2,801 young adult twins between 1999 and 2004 (T1) and 2,284 of the same twins between 2010 and 2011 (T2)...

OBJECTIVE: Traumatic events, particularly those that are interpersonal in nature, are associated with increased risk for co-occurring sequelae, including sleep disturbances, posttraumatic stress disorder (PTSD), and alcohol use disorder (AUD). However, the associations between these phenotypes have not been explored among college students. METHODS: We examined relationships between type of potentially traumatic event (PTE) exposure (pre-college) and sleep disturbances, as well as mediating effects of lifetime PTSD and AUD symptoms on these relationships, in a large undergraduate sample (N = 1599, 64...

OBJECTIVE: Alcohol use problems are common during adolescence and can predict serious negative outcomes in adulthood, including substance dependence and psychopathology. The current study examines the notion that alcohol use problems are driven by polygenic influences and that genetic influences may indirectly affect alcohol use problems through multiple pathways of risk, including variations in personality. METHOD: We used a genome-wide approach to examine associations between genetic risk for alcohol use problems, personality dimensions, and adolescent alcohol use problems in two separate longitudinal population-based samples, the Finnish Twin Cohort (FinnTwin12) and the Avon Longitudinal Study of Parents and Children (ALSPAC)...

This study examined the effect of parenting on the association between childhood sexual abuse (CSA) and psychiatric resilience in adulthood in a large female twin sample (n = 1423) assessed for severe CSA (i.e., attempted or completed intercourse before age 16). Severe CSA was associated with lower resilience to recent stressors in adulthood (defined as the difference between their internalizing symptoms and their predicted level of symptoms based on cumulative exposure to stressful life events). Subscales of the Parental Bonding Instrument were significantly associated with resilience...

Peter Zachar, Kenneth S Kendler
Many scholars believe that psychiatric nosology is undergoing a crisis of confidence. Some of the issues up for debate hark back to the introduction of the natural history approach to classification in the seventeenth century. Natural histories map sameness and difference rather than speculate about causes. In contrast, the natural classification approach aspires to carve nature at the joints by demarcating classifications by causes. Natural classifications are more ideal scientifically, but speculation about causality has had a poor track record in psychiatric nosology...

BACKGROUND: The ALDH2*2 allele (A-allele) at rs671 is more commonly carried by Asians and is associated with alcohol-related flushing, a strong adverse reaction to alcohol that is protective against drinking. Social factors, such as having friends who binge drink, also contribute to drinking in Asian youth. OBJECTIVES: This study examined the interplay between ALDH2*2, peer drinking, and alcohol consumption in college students. We hypothesized that the relationship between ALDH2*2 and standard grams of ethanol per month would vary based on the level of peer drinking...

Background: Maternal alcohol use during pregnancy has repeatedly been associated with development of attention-deficit hyperactivity disorder (ADHD) in the offspring. It is, however not known whether this reflects a direct casual intra-uterine effect or a non-causal relationship due to confounding. We used three different approaches to control for measured and unmeasured confounding: statistical adjustment for covariates, negative control comparison against maternal pre-pregnancy alcohol use, and comparison among differentially exposed siblings...
